Now to this I want to add my new DNS number. Add the following lines if they are not already there. If they are there than just change the numbers.
Normally the DNS is set to your ISP DNS or that of your Modem/Router

Your DNS numbers may vary depending on which DNS server you have chosen to use. Save your file and than close your editor.
Now in order to make them active we need to restart our network. To do this open a console window and change to the root user.
For those of you that are command line challenged simply reboot your computer
